Excel RANK Function
The Excel RANK function returns the rank of a numeric value when compared to a list of other numeric values. RANK can rank values from largest to smallest (i.e. top sales) as well as smallest to largest (i.e. fastest time).
- number - The number to rank.
- ref - The range that contains numbers to rank against.
- order - [optional] Whether to rank in ascending or descending order.
The Excel RANK function assigns a rank to a numeric value when compared to a list of other numeric values. Use RANK when you want to display a rank for numeric values in a list. It is not necessary to sort the values in the list before using RANK.
Controlling rank order
The rank function has two modes of operation, controlled by the order argument. To rank values where the largest value is ranked #1, set order to zero (0). For example, with the values 1-5 in the range A1:A5:
Set order to zero (0) when you want to rank something like top sales, where the largest sales number should rank #1, and to set order to one (1) when you want to rank something like race results, where the shortest (fastest) time should rank #1.
The RANK function will assign duplicate values to the same rank. For example, if a certain value has a rank of 3, and there are two instances of the value in the data, the RANK function will assign both instances a rank of 3. The next rank assigned will be 5, and no value will be assigned a rank of 4. If tied ranks are a problem, one workaround is to employ a tie-breaking strategy.
- The default for order is zero (0). If order is 0 or omitted, number is ranked against the numbers sorted in descending order: smaller numbers receive a higher rank value, and the largest value in a list will be ranked #1.
- If order is 1, number is ranked against the numbers sorted in ascending order: smaller numbers receive a lower rank value, and the smallest value in a list will be ranked #1.
- It is not necessary to sort the values in the list before using the RANK function.
- In the event of a tie (i.e. the list contains duplicates) RANK will assign the same rank value to each set of duplicates.
- Some documentation suggests ref can be a range or array, but it appears ref must be a range.
